Filming in Subzero Temperatures
The Walking Dead is filmed in cold or rainy weather. Nighttime filming is brutally cold because of the lack of insulation. The show isn’t set in a location that experiences temperatures that low, so post-production services are required. One excellent case in point is the second season’s “Beside the Dying Fire.” The temperature on set was so low that when the actors breathed steam would come out of their mouths. Digital breath removal was used by the episode’s editors to get the show ready for air.
